does anybody know an algorithm which calculates and returns all the possible combinations (NOT permutation) of the elements of an array?Here an example of what I need:
Code:
var arr:Array = [a, b, c, d]
var combinations:Array = [[a,b],[a,c],[a,d],[b,c],[b,d],[c,d],[a,b,c],[a,b,d],[b,c,d],[a,b,c,d]] //surely I have missed some combination...
does anyone know how to shift all the array elements by one or more without deleting the array itself?
Something like rotating the array:
1,2,3,4,5,6,7,8,9,10
10,1,2,3,4,5,6,7,8,9
9,10,1,2,3,4,5,6,7,8
8,9,10,1,2,3,4,5,6,7
7,8,9,10,1,2,3,4,5,6
I've been trying to move array elements from one array to another using the push method. The problem is that the element pushed should any longer be on the first array where it was taken from. That's where i'm stuck..

Is there a way to write out an array without the that separates the elements in the array?
View 15 RepliesIf I am a subclass of an Array, how do I access an element?
class ArrayOfFoo extends Array
{
public function getFooAt(anIndex : int) : Foo
{
return this[anIndex] as Foo; // <---- looks for an object attribute (named "0", for example)
}
}
I could wrap an array instead of subclassing it, however lacking a universal IArray interface, that is less than useful for standard and custom functions expecting an Array.
I'm using an "input array" to receive keyboard input from the user (keyboard events tag the character code in an array, and during input check phase, the procedure checks specific cells in the arrays).In my case, it works properly, but different key combinations don't work together![code]all combinations work together, besides when KEY_UP and KEY_CCW are pressed together (the one which was pressed before only responds) and the KEY_DOWN and KEY_CW combination. Anyone has a clue what's wrong?
View 1 RepliesDoes flash have some key combinations reserved? I am creating keyboard shortcuts and am discovering that some of the key combinations do not work. For example, Control + H does not work, but if I switch it to Control + L it works fine. I've found a few other Control + (letter) that do not work either. Is there a way to disable whatever flash has reserved so I can use whatever letter I want?

View 1 RepliesHow do you empty an array. I want the array complete empty, so the array length =0. I have tried this code, but that doesn�t take away all elements in an array, just a few.
for (i=0; i<myArray.length; i++) {
myArray.pop();
}

I'm revisiting some old code that filters XML, but this could easily apply to the parameters of a method (the way I'm using it, it essentially is). This is a problem I feel like I run into a lot and don't know a good way around this. So the problem is that I've got 3 arguments. They're all optional. I want to see which ones are presents and test if their values based on which ones are present (sorted according to likelihood):

I've searched high and low for a simple function that gives me all the possible combination of a set of characters with no avail. Anyone here got enough of a maths brain for this one? I want a function around the likes of this: possibleCombinations("abc"); which returns an array: "abc", "ab", "a", "cba", "cb", "c", "..."

View 2 RepliesI´m trying to order elements of an array. When the dates come from dynamics text it´s no problem, bad when come from input text the dates are treated like strings and it´s impossible to order correctly, because 15 is considered less than 3. In both cases I can operate correctly whit this dates like numbers.How is possible to order this dates from input text, like numbers?

I'm writing an application in Flex / ActionScript and have a number of class member variables of type Array storing data. My question is: what's the "best" way to clear out an Array object? I noticed the ArrayCollection class has a function removeAll() which does this, but the basic Array class does not. Some possibilities I've considered are:
Iterating through the array, calling pop or shift on each element
Setting the array length to 0
Setting the member variable to a "new Array()" or "[]"
var count:uint = 0;
var textInputs:Array /* of TextInputs */ = [];
for(var i:String in columnsData){
[Code]....
here how can i access the first, second of Array of textinputs in the form of string or any thing to further proceed

I have one array with many elements inside.
ActionScript Code:
var all_id:Array = new Array ["56","42","35","64"];
I also have one cd id, which is dynamically created.Im trying to create a function, which checks if the cd id matches any of the IDs of the array.
ActionScript Code:
for(i=0; i<all_id.length;i++){
if(all_id[i] == id){
trace("ID MATCH");
[code]....
My problem is that - because I'm looping through the elements, I get several traces.Is there a way to get a result if any element matches?

View 2 RepliesI can set them up and even partially delete items (there value is replaced with "undefined") in the array but not thier index. What i want to accomplish is to have a number of words in array that are randomly chosen one at a time and only one time each on the press of a btn.
So if the array contains the words; the, go, see, a
The first press of the button might choose the word "the". Which would remove it from the list and the next press of the button would randomly choose one of the remaining words; go, see, a.
I have an array myArray:Array = [no1_mc, no2_mc,no5_mc];I have a variable imageNumber:Number which gets values from 1 - 5 or 5 - 1 depending if next_mc or prev_mc is clicked.Now, next_mc will load a next image and prev_mc will load prev image.What i want is that depending on the value of the variable imageNumber i want to toggle the alpha of the movieClips inside the array myArray.So if imageNumber = 3, then no3_mc.alpha = 1 while the remaining mc's alpha = 0.5.

I have created an application using Flash CS3 and Actionscript 2.0 that uses an XML file to display employees names, photo, and job title. I have also implemented a search feature that allows users to search for names, etcWhen the user executes a search, the results populate a dynamic text field. I would like the users to be able to click on one of the results and have it pull up that persons corresponding photoAt the moment, users are only able to navigate through photos using a Next and Previous button.So the question is, how do I allow for individual elements in an array to be clickable links that bring up the data? Here is what a portion of the code looks like (the function "displayresults" is the function that I need to modify to work, it currently only brings up the last image in the array):
Code:
function DisplayNodes (nodes, field_txt){
field_txt.htmlText = "";
